Hi All - upgraded to an Intel i5 2400 CPU with ASRock P67 PRO motherboard. Everything went well, Windows found everything and installed the drivers fine apart from one.

In the System there is a Canon LIDE scanner which shows as a CanoScan with the yellow exclamation mark. Also Devices and Printers it shows up but with the yellow exclamation mark. Have reinstalled the supplied 64bit Canon software for it but still no go. It is USB powered so swapped around the USB cable but still a no go area. Unplugging and reconnecting the scanner makes no difference. I have no idea where Canon places the drivers for this when the set up program installs.

Going online Windows finds the driver software but reports back that it has encountered an error while attempting to install it. The software it is tryng to install is CanoScan LiDE 600F.

Does anyone have any ideas why this thing should suddenly stop working. Everything else is fine. Any input appreciated as I'm loosing more hair over this.
